As far as I know, there is no way to make a T1000 modem do compression. I know that you can set ATS110=1, but if you then do ATS110? the response is 000. It is rather telling that AT&n omits the S110 register on the T1000. The T1000 also is limited to about 880 char/sec or so no matter what sort of PEP device is on the other end of the line. It appears that when the connection is negotiated with the other end, the T1000 sets about half of the carriers to 0 bits per carrier. I don't have a T1000 here to open up, but something tells me that the computing metal inside is susbstantially less than the 68000 and DSP chip in the Trailblazer Plus or the T2500. Actually, the system used to make the T1000 compatible with other PEP modems seems rather clever to me. For curiosity's sake, anybody care to comment on just what hardware is inside a T1000? Bill
